In the above figure, the X direction, the Y direction and the Z direction are perpendicular to each other. Figure 1-Figure 4 This embodiment provides a material suction device. The material suction device includes a support mechanism 100, an adjustment mechanism 300 and a plurality of adsorption mechanisms 200. The plurality of adsorption mechanisms 200 are arranged in the support mechanism 100 with adjustable spacing along the X direction, and the adsorption mechanism 200 can partially extend out of the support mechanism 100 to adsorb the material to be adsorbed. The adjustment mechanism 300 is installed on the support mechanism 100 and connected to the adsorption mechanism 200, and can adjust the spacing between the plurality of adsorption mechanisms 200.

[0046] Figure 5 A partial structural schematic diagram of the adjustment mechanism provided by an embodiment of the present invention is shown. Figure 6 The schematic diagram of the structure of the adsorption mechanism provided by the present invention is shown. Figure 7 The schematic diagram of the assembly of the adsorption mechanism and the adjustment mechanism provided by the present invention is shown. Figure 4-Figure 7 The adjustment mechanism 300 includes a mounting plate 310 and a plurality of convex rib structures 320. The mounting plate 310 is connected to the support mechanism 100 in a height-adjustable manner in the Z direction. The plurality of convex rib structures 320 are arranged at an angle to the Z direction. The adsorption mechanism 200 corresponds to and is connected to the convex rib structures 320 one by one. The adsorption mechanism 200 can slide relatively along the corresponding convex rib structure 320, and the position of the adsorption mechanism 200 in the X direction can be adjusted under the drive of the movement of the mounting plate 310 in the Z direction.

[0047] Specifically, the support mechanism 100 includes a top support member 120, a side support member 130, a bottom support member 140 and a back support member 150. The top support member 120 and the bottom support member 140 are arranged parallel to the XY plane and are arranged at intervals in the Z direction to form a receiving space. The side support members 130 are two, which are respectively arranged on both sides of the receiving space in the X direction and are sandwiched between the top support member 120 and the bottom support member 140. The back support member 150 is arranged parallel to the Z direction and is arranged on one side of the receiving space in the Y direction to form a receiving space with one end open. A plurality of adsorption mechanisms 200 are arranged in the receiving space and can partially extend to the side of the bottom support member 140 away from the receiving space to adsorb the material to be adsorbed. Another part of the adsorption mechanism 200 can pass through the back support member 150 and be positioned in the Z direction by the back support member 150, and this part can be connected to the rib structure 320 and slide relatively.

[0048] To be more specific, a guide rail 110 is provided along the Z direction on the side of the back support member 150 facing away from the accommodating space. The adjustment mechanism 300 also includes a slider 330. The slider 330 is fixedly connected to the mounting plate 310 and is located on the same side of the mounting plate 310 as the rib structure 320. The slider 330 is slidably connected to the guide rail 110.

[0049] Preferably, the number of the guide rails 110 is two, and the two guide rails 110 are spaced apart in the X direction and are respectively disposed on both sides of the back support 150. The number of the sliders 330 is also two, and the two sliders 330 are spaced apart in the X direction and are respectively disposed on both sides of the mounting plate 310 to avoid the rib structure 320. The cooperation of the two sets of guide rails 110 and the sliders 330 can improve the stability of the movement of the mounting plate 310 relative to the back support 150.

[0050] More specifically, refer to Figure 3 , Figure 5 and Figure 7 , in the Z direction and in the direction where the height gradually decreases, the spacing between the multiple rib structures 320 gradually decreases. That is to say, with the center point position of the lower edge of the mounting plate 310, the multiple rib structures 320 are distributed in a divergent shape. When the mounting plate 310 is lowered in the Z direction relative to the back support 150, the multiple adsorption mechanisms 200 can move away from each other under the limiting effect of the back support 150 in the Z direction and the movable cooperation with the rib structure 320, thereby increasing the spacing between adjacent adsorption mechanisms 200. When the mounting plate 310 is raised in the Z direction relative to the back support 150, the multiple adsorption mechanisms 200 can move closer to each other under the limiting effect of the back support 150 in the Z direction and the movable cooperation with the rib structure 320, thereby reducing the spacing between adjacent adsorption mechanisms 200.

[0051] Continue to refer to Figure 1 , Figure 2 , Figure 4 and Figure 5, the adjustment mechanism 300 also includes a driving assembly 340, a transmission screw (not shown) and a screw sleeve 350. The driving end of the driving assembly 340 is fixedly arranged on the top support member 120, and the rotation output end of the driving assembly 340 is arranged along the Z direction and extends to the bottom of the top support member 120. The transmission screw is connected to the rotation output end of the driving assembly 340, and can rotate around its own axis under the drive of the driving assembly 340. The screw sleeve 350 is screwed and sleeved outside the transmission screw, and is fixedly connected to the mounting plate 310. Through the above arrangement, when the transmission screw rotates under the drive of the rotation output end of the driving assembly 340, the screw sleeve 350 can move along the transmission screw in the Z direction, thereby driving the mounting plate 310 to move.

[0052] Specifically, the suction device further includes an origin sensor 400, which is disposed on the side support member 130 at one end of the support mechanism 100 in the X direction. The origin sensor 400 is communicatively connected to the drive assembly 340, and can send an initial position signal. The drive assembly 340 can use the origin sensor 400 as a starting point to adjust the spacing between the plurality of suction mechanisms 200.

[0053] More specifically, Figure 5 and Figure 7 As shown, the mounting plate 310 is provided with a clamp structure 311, and the lead screw sleeve 350 is fixedly clamped in the clamp structure 311. In this embodiment, the clamp structure 311 is specifically arranged at the middle position of the mounting plate 310 in the X direction, and is arranged close to the upper edge of the mounting plate 310 in the Z direction. By clamping the lead screw sleeve 350 and the clamp structure 311, the mounting plate 310 can be detachably connected, thereby improving the flexibility of the suction device.

[0054] Reference Figure 6 and Figure 7 , the adsorption mechanism 200 includes a support structure 210, a sliding structure 220 and a suction nozzle structure 230. The rear end of the support structure 210 can pass through the back support 150 and can be slidably connected to the corresponding rib structure 320. The sliding structure 220 is movably connected to the support structure 210 along the Z direction, and the suction nozzle structure 230 is connected to the bottom of the sliding structure 220, can pass through the bottom support 140, and extend to the side of the bottom support 140 away from the accommodating space, so as to adsorb the material to be adsorbed. In this embodiment, the sliding structure 220 can specifically be a slide cylinder, which is provided with a sliding groove, and the sliding groove extends along the Z direction. The support structure 210 is provided with a sliding convex strip, and the sliding convex strip extends along the Z direction. The sliding convex strip can be slidably accommodated in the sliding groove, and the sliding convex strip can move along the sliding groove.

[0055] Specifically, the adsorption mechanism 200 further includes a follower assembly 240, which includes a first roller 241 and a second roller 242, the first roller 241 and the second roller 242 are arranged at intervals and are both rotatably connected to the support structure 210. The convex rib structure 320 is sandwiched between the first roller 241 and the second roller 242, and the first roller 241 and the second roller 242 can roll along the convex rib structure 320.

[0056] More specifically, in this embodiment, the back support member 150 is provided with a waist-shaped long hole, and the long axis direction of the waist-shaped long hole is parallel to the X direction. The support structure 210 is provided with a portion of the follower assembly 240 that can extend from the accommodation space through the waist-shaped long hole to the side of the back support member 150 away from the accommodation space. The waist-shaped long hole can position the support structure 210 in the Z direction to prevent the support structure 210 from moving in the Z direction.

[0057] More specifically, the spacing between the first roller 241 and the second roller 242 is adjustable. In this embodiment, the rotation axis of the first roller 241 is disposed along the Y direction at the end of a portion of the bracket structure 210 extending out of the waist-shaped long hole. The second roller 242 is connected to the bracket structure 210 through an eccentric shaft screw and the like, and the rotation axis position of the second roller 242 can be fine-tuned through the eccentric shaft screw, thereby adjusting the spacing between the first roller 241 and the second roller 242.

[0058] More specifically, the suction mechanism 200 further includes a limiting structure 250, which is connected to the side of the sliding structure 220 and can move along the Z direction with the sliding structure 220. A limiting boss 212 is provided on the support body 211 of the support structure 210, and the limiting boss 212 is located on the moving path of the limiting structure 250 and can limit the lower limit of the displacement of the limiting structure 250. Through the cooperation of the limiting structure 250 and the limiting boss 212, the length of the nozzle structure 230 extending out of the bottom support member 140 can be limited.

[0059] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
